There were two HAVE BLUE aircraft. Both flew at Groom Lake (Area 51), although the media will only say they flew at a 'secret testing facility in Nevada,' and were probably responsible for some of the Area 51 sightings made around 1980. They were completely unlike any aircraft then known, as they were the first designed using nothing but flat panels and straight edges - their shape was dictated by the requirement to keep a low radar cross-section.

Although the HAVE BLUE team was sure of the plane's design as it applied to the radar cross section, no one had yet tried to make the ungainly thing actually fly until then. The HAVE BLUE was fully fly-by-wire, as (like its younger and larger brother the F-117) the HAVE BLUE is dynamically unstable in the air and requires computer support to remain controllable.
